I got Rituxan in December. Two treatments four weeks apart. I got much better right away, but improvement has seemed to dwindle a little over the past few weeks. I had blood drawn this week to check for cd19 and cd20 cells. If they have returned, I will get more infusions.

I did have an allergic reaction during the first infusion, but IV Benadryl took care of it. Allergic reaction is more likely to occur during the first infusion, when they speed up the drip. On the second infusion they did not exceed the previous safe rate and I had no reaction.
Be sure to ask for Tylenol, solumedrol and Benadryl pre meds. My dr. didn't order them, but I had researched and knew to ask for them.
If you have any more questions, please ask.
